About the 525 nm Wave Rotator Plate 90°
- Can be used with a PBS cube for polarization combining
- Cost-effective and easier to align alternative to traditional polarization half wave retarders (λ/2 waveplates)
- V-AR coating allows transmission >99% (typ.) near 525 nm
Half wave polarization rotators function by rotating the polarization axis of linearly polarized light by 90 degrees (lambda/2) at and near the design wavelength.
Polarization rotator plates are an excellent and far lower-cost alternative to a waveplate retarder. However, unlike traditional waveplate retarders, the rotation of the polarization is independent of the angle of the optic about the z-axis (light propagation axis). This makes alignment much simpler compared to working with a half waveplate retarder.
Our half-wave polarization rotators commonly used to combine beams in conjunction with a polarizing beamsplitter (PBS) cube for the same wavelength. This is a cost-effective means to effectively double the power in an optical system without a loss in etendue or increase in divergence.
Although the design wavelength is 525 nm, this product may be used at the 514 nm, 515 nm, 520 nm and 532 nm wavelengths with minimal loss of efficiency. This polarization rotator plate has dimensions of 10 x 10 mm with a nominal thickness of 3 mm, rendering it suitable for large or multiple beams adjoined by “knife edging”.
Opt Lasers also offers half-wave polarization rotators at 455 nm and 638 nm, as well as PBS cubes at the 455 nm, 525 nm and 638 nm wavelengths.
